improved Machine for Making Coiled-Wire Ferrules, of which the following is a full, clear,

and exact description. I

Referenceis to be had to the accompanying drawings,forming a part of this specification,

in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of my improvement,

:parts being broken away. Fig. 2 is a side elevation of the same, partly in section. V Fig. 3 is a side elevation ofthe. polishing-brush and its drivingpulley and. supporting-bar.

. Fig. 4 is a sectionalside elevation of the wireguide and the jacket. Fig. 5 is a side elevation of the hollow split mandrel. Fig. 6 is a sidezelevation of a part of a completed lferrule. Fig. 7 is a view in elevation, showing apart of the mandrel, its support, and gearing in thesolder.

The object of this invention is to facilitate the making of coiled-wire ferrules.

The invention consists in a machine for making coiled-wire ferrules constructed with a mandrel revolved by suitable mechanism with in a stationary-band having an inclined upper edge to raise the wire as it is coiled and form a space for the next coil.

The band and the lower part of the mandrel are surrounded by a jacket having apertures to admit solder, and a slot to receive the wire to becoiled, andwhich serves as a guard to keep the coiled wire in place as it moves up the mandrel. The upper part of the mandrel is made tubular, and is slitted from its upper end, so that the said mandrel can be kept cool more readily, and will allow the coiled wire. to be moved upward uponit more easily. The machine is providedwitha-brush rotated from the driving mechanism of the mandrel for brushing the uncombined solder from the coiled wire upon the upper part of the said mandrel and polishing the said wire, as will be hereinafter iullydescribed.

Arepresents the frame of the machine,whicl1 is designed to be bolted to the sides ofa vat, 13, containing molten or liquid solder, or to pth'er suitable supports. The middle part of the frame A is depressed, and to it is pivoted the lower end of the mandrel G, the upper part of which is-made. tubular, an-d is-wsplit from its upper. end nearly to its lower end, and is made of steel or other suitable elastic metal, to allow it to be compressed'for convenience in slipping oifthe completed ferrule.

IfdesirecL-the free upper ends of the strips of the mandrel O can be supported by a spring to hold the said stripsagainst the pull: of the wire while being coiled. The mandreLG is supported in an erect position by a bearing, 1), formed in a cross-plate of theframe A.

To the bearing-plate D is bolted the baseflange of the jacket E, which has a number of in Fig. .1, so that the wire H will come in con-- tact with the said mandrel in proper position to be coiled upon it. The interior of the jacket E is made so much larger than the mandrel G as to allow the coiled wire to slide freely up the said mandrel, and to adapt the said jacket to serve as a guard to keep the said coiled wire in place while sliding up the mandrel.

In the lower part of the jacket E is placed a band, I, which is secured to the said jacket by a set-screw or other suitable means, in such a position that its upper edgewill be about upon a level with the point at which the wire H comes in contact with the mandrel. The upper edge of the band I is inclined, the pitch of the inclination being such that the vertical shoulder joining the lowest and highest points of the said edge will have a length a little greater than the diameter of the wire to be coiled, and the direction of the inclination be ing such that the wire H will pass to the mandrel 0 across the vertical shoulder of the said edge, and come in contactwith the mandrel below the last coil of the wire, the inclined edge of the band I pushing the wire upward as fast as it is coiled.

The machine is designed to be in molten solder to such a depth that the ensubnierged perforations, F, formed in it to allow the sol tering-point of the wire and the lowest two or three coils of wire upon the mandrel G will be beneath the surface of the solder. As the soldered coils of wire rise above the jacket E, they are designed to be subjected to a blast of air from an ordinary fan-blower to cool the wire and allow the solder to harden quickly. The tubes of soldered coiled wire are made in pieces three feet (more or less) in length, and are afterward cut into ferrules of the desired length.

To the lower end of the mandrel O is attached a gear-Wheel, J, the teeth of which mesh into the teeth of a gear-wheel, K, attached to the lower end of the vertical shaft L. The shaft L revolves in bearings in bars or arms attached tQror formed upon theframe A, and to its upper part is attached a beveled-gear wheel, M, the teeth ofwhich mesh into theteethof the beveledgear wheel N, attached to the inner end of the shaftv O. The shaft 0. revolves in bearings formed upon. or attached to the arm 1?, secured to; the frame A. To the outer end of the shaft 0 is; attached a pulley, Q, to receivea drivingbeltwjllen the machine is to be driven by power, or a crank whenthe machine is to be operated by hand. As the tube of coiled wire asses to theupper part of the mandrel C, it it: Wiped' by a rotating brush, R, attached to the lower end of a. short shaft, S, which revolves. in bearings in a bar or arm, T, secured to the frame A.

To the upper end of the shaft S is attached apul-ley, U, to receive an endless band, which also passes, around a pulley, V, attached. to the upper end of the shaft L, so that the said brush; will. be driven from the driving mechanism of; the machine.

The endless band is not shown in the drawi gs.

Having thus described my invention, I claim as. new and desire to secure byLetters Patent-e ;l-. The mandrel O of a machine for coiling wire ferrules, made tubular and of elastic 7 rules, the combination, with the rotary manv drel O and the stationary band I, having inclined upper edge, of the jacket E, having apertures F to admit solder, and an inclined slot, H, ,to receive the wire, substantially as herein shown and described, whereby the coiled wire is kept inplace as it is pushed up the mandrel, as set forth.

4. In a machine for making coiled-wire ferrules, the rotary mandrel 0, made substantially as herein shown and described, with its upper part tubular and slitted longitudinally from its upper end, whereby the mandrel can be kept cool more readily, and will allow the coiled wire to move upward: upon it more easily, as set forth.

5. In a machine for making coiled-wireferrules, the combination, with the rotary mandrel O and its driving mechanism, of the rotarybrush R and its driving mechanism, su-b stantially as herein shown and described,

whereby the uncombined solder is brushed off and the coiled wire is polished, as set forth.

(5. In a machine for coiling wire ferrules, the combination, with the mandrel 0, bearing D, and jacket E, of a stationary band, I, inclined at the upper edge to push thewire up.- wardly as fast as coiled, as described.
